The laboratory vacuum spray dryer has been developed for heat-sensitive materials, and the whole machine has a compact and self-contained design, which can be operated without additional facilities. One-button start-up, color large LCD touch screen operation, convenient operation and monitoring of the experimental process, realize the instantaneous drying of materials under low temperature conditions (50), and provide convenient and safe drying methods for heat-sensitive materials, such as enzyme preparations and other biological products, sugar-containing natural product extracts of traditional Chinese medicine, polymer materials that are not heat-resistant, materials that are vaporized when heated, etc. The atomization structure and applicability of the low-temperature spray dryer.
The low-temperature spray dryer is very suitable for the production of trace granular powder in the laboratory of research institutes, universities and food, pharmaceutical and chemical enterprises, and has broad-spectrum applicability to all suspensions and emulsions when used, and is suitable for the drying of heat-sensitive substances such as biopharmaceuticals, biopesticides, enzyme preparations, polymer materials, etc.
The low-temperature spray dryer mainly uses its color LCD touch screen parameter display in the process of production, the whole equipment is powered on by one button, after setting the spray process parameters, the temperature reaches the predetermined temperature, the peristaltic pump is started, the touch screen is displayed, and the operation process is clearly displayed.
The low-temperature spray dryer is effectively equipped with a nozzle cleaner, when the nozzle is blocked, it will be automatically clear, the frequency of the needle can be automatically adjusted, the equipment only needs to press the stop button in the process of shutting down, and the machine will stop running immediately except for the fan, so as to ensure that the equipment will not be burned out due to misoperation.
The drying, spraying and collection system of the low-temperature spray dryer is mainly made of transparent high-quality stainless steel materials, which will make the drying process in a pollution-free environment, with a built-in oil-free air compressor, the particle diameter of the powder spraying is normally distributed, the fluidity is very good, and the noise is very low, less than 60db
The low-temperature spray dryer adopts the atomization structure of two-fluid spray when making, the whole machine is made of its high-quality stainless steel material, the design of the whole equipment is very compact and does not need auxiliary equipment, and the design of temperature control adopts real-time control PID constant temperature control technology, so that the temperature control of the whole temperature zone is accurate.
Technical features: 1. The whole experimental process of spray drying is completed in a vacuum environment, which reduces the drying temperature of materials and solves the problem of spray drying of heat-sensitive materials. 2. Color touch screen operation: heating temperature PID constant temperature control, peristaltic pump feeding speed can be adjusted at any time. 3. Built-in oil-free air compressor, the particle diameter of powder spraying is normally distributed, with good fluidity and low noise, which meets the laboratory noise standard4. The spray head is a concentric spray head, which is atomized to ensure that there is no eccentricity that causes it to be sprayed to the side of the bottle wall, and the spray head can be moved up and down after installation, so as to adjust the atomization position and improve the spray drying effectThe atomization structure of the two-fluid spray is made of stainless steel material, with compact design, no auxiliary equipment, easy to use, and as good as new. 5. In order to meet the user's requirements for adjusting various parameters in the experimental range, real-time control PID constant temperature control technology is adopted in the design of drying temperature control, so that the temperature control of the whole temperature zone is accurate, and the heating temperature control accuracy is 1. 6. The feeding capacity can be adjusted by the feeding peristaltic pump, and the rated processing capacity is 800ml h
